I agree you did well for a first attempt.. Now you do need to practice if you
wish to draw well.
Remember to draw for fun along with the practice. Try drawing other characters.
Look at how others draw your species of choice. It's a good way to gain ideas for
your own artwork. Also draw different poses. Sometimes people get stuck drawing
profiles or face on stiff drawings. These are easier, but you will learn more doing
other positions and action poses as well.
If you want to do realistic art, you will need to study anatomy for the species you
like along with that of humans if you wish to do anthro art well.
There are several toutorials online for furry art which can be helpful too.
Don't forget to post your work, we can help by pointing out things that you may
need to work on. Don't get discuraged, drawing like any craft takes time to learn.
Keep up the good work.
