Yes, absence of tail was most certainly the first thing I noticed.
The walkcycle itself is ok, but the legs seem to be going in a back and forward motion rather than in a circle. If that makes any sense. If you watch people's feet when they walk, the feet themselves make a circle. If you try to keep in mind that the motion of the feet should form a circle (elipse, rather) then you should be able to work out motion of knees and hips afterwards. At least that is how I do it.
As a bit of a branch of from the move toward realism posted by Al_Ninio (which still leaves him looking a tad hunchbacked), I thought you could perhaps go all the way cartoony, and give him human-esque proportioned. To show what I mean:

Obviously the lines are a bit basic and so is the shading, but MSPaint is my master and I must obey its every word.
I think you're doing well. If you can draw like this at 13, you'll be showing us how its done in a few years time. Keep practising and you'll do very well. And dude, you're another West Aussie!!! Good to see a fellow countryman (and stateman or whatever) around the AGS forums.
