That's really not impressive... you just copy/pasted a riley sprite onto a bike... that takes a whole five seconds... depending on how slow your computer is...
Regardless, the sprite looks nice, but still, it would be nice to see a bit more difficulty level. Try something a bit harder... if you're into ow's, maybe try scratching your own... or at least making edits and fusions to start...
BTW, as much as it pains me to say this, you need 4+ sprites on this thread or else one of are good moderators will swoop in like a fearow out of hell and close this down :(
Don't get discouraged, just try something new, and a bit tougher!
Keep Spriting!
