Welcome to the forum. I'm sorry we didn't see your post right away--if you're new, I suggest posting on the greetings thread first, and then posting here for artwork advice, like Loc and OldRabbit suggested.
If you delete your image, we can't help you out. If you want us to give you pointers, we can, provided we see something to work with.
I hope you stay on the forums despite being shy.
All the best,
