You can always post the images of your art on an external image hosting site, like imgur or photobucket, or even facebook, and then just embed the image in your posts. That's how I get mine into my art thread.
And I do scans of my drawings, so the files are pretty massive compared to the maximum attachment size here.
As for your drawing itself, there is certainly no shortage of emotion in your fursona.
And I can tell you have the same problem with hands that I do, hehe. I'm still working on how to draw them well, so if I'm having a bad hand-drawing day, I'll just shove them in pockets or put them behind the back, like I did with my left paw in my avatar.
I'd advise you to keep experimenting, though. Don't be afraid to take risks in your drawings, for that is the only way you'll truly sharpen your skills. Try out different angles, expressions, and positions. You never know where your pencil will take you, so if a drawing goes in an unexpected direction, just roll with it and see what you create.
