Hey, sorry for the late response. Will look into it now.
So for the full scan, it may not be the same as other reviews due to it being a cosplay, then there's a different pattern on how to look at the avi. But will attempt!
Full scan:
Back -> top -> bottom
So I haven't watched Cowboy bebop myself, but was the BG intended to be like part of the space ship? (if such even exists in the series) Iv'e watched some clips from the series, and seen some scenes which has a background similar to that on you are using currently. And this one may be the closest on Gaia has to such, so i'd say it's a nice choice and couldn't be picked better in terms of BG's.

what's wrong: The only part on your avi I think could be improved would be your hair part, I reckon gaia has a hairstyle which is even more similar to that of in the series, than the one you got currently. But I'm no hair expert, so I don't know the name for certain, will look into it and see if I find anything. It also seems the yellow head/hair - band gets overlayed, but that can't be helped as we can't control which item should layer which.
Face: It's really detailed, clear eye colour, visible nose and extremely visible lipstick colour, last but not least a cigarette to top it off!. The face feels really "filled out" so that there aren't any empty spots to it. Usually the face is the hardest area to pull of but flows here.
Torso: I suppose the black strings are part of the torso wear, (red clothing) either way, it does seem to flow really well with the yellow bra you are wearing underneath, and by saying such I mean it doesn't seem distracting in any ways, even though it's the only black your avi is wearing. Also the red semi-top is a really nice item choice, it doesn't cover the whole torso, as many torso-wear items would do, and it's probably one of the best possible items to use for the character.
Handhold: At first glance I didn't notice the handhold, the way it's posed and the BG colours, it seems to clash well against each other. (the gun almost felt like a mechanical part of the background) have you tried having it on another pose? just to make it more visible that is.
Leggings: Not too much to say here, but on the top part of your leggings you are wearing "Fallout Trickster" sort of semi-shorts ey? It's a nice yellow touch, and as the reference pic shows she does wear yellow there. So it's very fitting
Shoes: I don't know how her shoes look, but it looks fine on the avi's overall look.
Overall verdict: I think you nailed it pretty hard on many parts, there are some few places i'd like to see a tweak, but apart from that you spiced it further up on different areas like the face (Added cigarette) to make it even better.
Suggestions
You said you wanted to have a better yellow top. I looked around for some. (tektek down currently) the best I could find was "Fallout trickster"'s top bra thing. But apparently you are using the "Fallout tricksters" semi-shorts pose or what it's called. But that item has the perfect colour for the reference avi. I couldn't find any better yellow bra than this.
So my best suggestion here would be: have you considered swapping the semi-shorts in the fallout trickster pose, to the bra instead, and look for yellow shorts that is? perhaps that can solve your problem, due to looking for yellow shorts may allow even more item choices Ey? (Best solution I can think of currently) Gaia doesn't offer many top items in yellow, except whole T-shirts.
------------------------------
For
Number: 9.5/10 - You got it really close, many of the details are perfect. The only thing i'd like to see a tweak on would be the haircut if possible, & the gun pose/positioning.
Sorry for the delay on this review again.
