Welcome to Gaia! ::

Three Terra Formings for three field spells is massive overkill on your spell lineup. Needs reducing.

Try getting copies of Mystic Box to replace Shien's Spy. A lot more handy and it can be one of the most hated combos with your opponent. Ameba used in combo with the Box to get rid of an opponent's monster then hit them for 2000 LP worth of damage. Then quite possibly tribute the ameba and another monster (if you've used one of the Trio already) for Golem.
Hit 'em for an almost automatic 3k worth of damage.

There are a few cards that aren't the best choices for this deck and they can easily be replaced with something better.

Monsters:
The lineup is pretty much good for your basic burn.
No changes for me to recommend. Others might have ideas on what could be better.

Spells:
Like I said, reduce the Field Spell presence. It might be useful in powering up your monsters but you want to focus more on direct damage than anything else.
-2 Terra Forming
-3 Shien's Spy

+2 Wave Motion Cannon (S/T desruction bait and more burn if you can keep the sucker for about three turns)
+2 Mystic Box
+1 Heavy Storm (Good to clear up for an attack if you can manage one)

Traps:
-1 Destruction Ring (Bad card in general)
-1 Solemn Judgement (You want to survive longer and you don't really need the negation.)
-1 Ultimate Offering (This seemed sort of thrown in to me. Use this only if you want a Cannon Soldier/Gadget Barrage combo)

+2 Ojama Trio (These are wonderful in this deck scheme. They give you more to work with when it comes to Lava Golem not to mention they clog up necessary soace on your opponent's field.)
+1 Ceasefire (A WONDERFUL burn card.)
