OK, thicken your skin and lets go for a ride:
I see shading and and highlighting - that is a good thing. It looks like you are layering?
The skin tones are not bad and the one eye looks pretty good (for that mini). I\'d like to see the other one to see that they are pointed the same way.
Color selection is not great - the axe handle blends into the beard and gets lost. The helmate wings came from the same pots of paint as well? Limited pallet is tough to pull off without looking like you only own 3 pots of paint. Try a different base under the wings with the same mid tone and highlight to give them a different feel.
Photography: Ouch. You need to work on your photo skills a lot. Sorry, but a great mini with a bad pic won\'t score. A poor mini with a great pic will get the score it deserves. Read the articles section here, there are a couple of good tutorials there. Does your camera have a macro mode (little flower icon)? Are you using a tripod? Try my sig for a link to a photo tent and a background you can print out - although your background is not bad.
Basing - if nothing else, paint the top of the base to look like cobblestone or brick. Spend a couple of bucks on some flock or gather some sand from the local playground (sift out the cat bombs). As DR said, there are a lot of great painters here that are used to seeing a finished base that accents the mini.
All-in-all: not bad. I\'d score the mini between a 5 or 6, minus 1 for no base, minus 1 for the poor pic so it looks about right to me. You\'ve got lots of the basics down and should improve with pactice. Much like playing the piano or the x-box, you generally only get better by doing.
