Sonic Riders Style Goku!

[NICKtendo DS]

LOL Dude its FOR a flash Sonic Riders Game and yes it is my 1st post here I posted it to see how ppl can help me improve and it just being goku on an extreme gear is the POINT of it and I MADE ALL OF THOSE EXTREME GEAR MYSELF!! so dont come in here saying that i took the board sprites when i DIDNT. IT is supposed to be in sonic advance style I think i didnt explain correctly tho but chill next time ok im a beginner here and i learned somthin ok?

It was my point that the only thing you made was the board. I was unaware of the Flash game, though there are millions of fangames on the internet, only a few of which are decent IMO.
I could make a Sonic fan character for a Sonic fangame (I did, actually), which is perfectly fine. However, just because it has use in my fangame doesn't mean someone even thinks of wanting to use it for a comic or game of his or her own, hence I don't do it. This is to back-up oB2Kojjiro Mario's post.
My feedback on the board: it's flat. There's a lot that needs to be improved, I'll leave it to the experts to go into detail. Try shading it, apply some anti-aliasing and get a better green, cyan and yellow, since the ones I'm looking at right now is giving me a headache. And try to let the fire look like fire. Search for fire sprites similar to the ones you're looking for (don't copy-pasta), study it and see how you can make a flame. It's not too hard and anything's better than a cyan, solid triangle.
