waaaay too big imho. Really need to work with canvas alot smaller than that. Atm all the stuff u seem to be doing is pretty basic which is fine for a beginner but they just need more. You need to work on text alot. I've said this a few times here. Don't touch it with so much as a barge poll until your more experianced. start with some of the tutorials here and then move on to places like deviantart for some more advanced stuff. Look forward to seeing more work from you.
