Better, this angle seems easier for you and you made the eyes more natural looking on this one.
Looking at all your work so far, I have a few good suggestions for you though.
It looks like you could use some better brushes. I know the type that comes with kits - sometimes they're ok, but you need more of a selection to work with. Go to a nice art and craft supply store (Michaels, Hobby Lobby, or whatever you have there) and take a look at the higher quality brushes. Don't be turned off by the $5-20 cost per brush, you'll get what you pay for. Synthetic is ok for acrylics since it's a thicker paint. Get some smaller detail brushes.
Avoid the cheaper prepackaged ones.
Canvas is expensive, so that might keep you from practicing enough for you to keep improving your skills. Try looking for acrylic paper. It's comes in pads but the cost usually averages out to $1-3 per sheet ($10-20 for a medium sized pad of 10 sheets). There are some people who do wonderful work on paper, myself - I prefer it to canvas.
For some of your other paintings-
Try not to use black for painting some stuff if you can avoid it. If you want it to have some dimension to it you'll need to add highlights and shadows -you can't shade something that's already black. Other dark colors, like a dark brown or grey, will give you more room to work.
But this will get easier for you with practice.
Go to your local library and look for art books. You would benefit from learning basic concepts, color, lines,balance, focal point, etc. Get books on painting - preferably with acrylics, and a few on drawing - focus on realism (animals and humans) if that's what you want to improve.
You could use a little sketch pad too, just to sketch down your ideas that may come to you when you're not at home.
Keep working on your skills, practice will make you better and your feel for the paint and brush will improve as well.
