Well it has more texture, but it's obvious and messy (a Photoshop grassbrush does not fur make, and its obviousness takes me away from the actual painting). In some places the frost-y texture looks pretty nice, especially in the chest armor, but overall I'd tone down using textures brushes, don't let them steal the show from the actual figure and flatten all the forms.
Tinybird has hit the nail on the proverbial head. There's lots that I like about this - interesting design - nice menacing pose - he has a real sense of weight about him, but you need to focus more on fundamental drawing skills and avoid photoshop tricks.
The biggest problem with the painting is a lack of 3D feel - this comes down to lighting. I haven't seen anything else you've done but judging from how you've approached this piece, you probably need to do some still life drawing to improve your understanding of light. Draw some eggs Get an understanding of light and dark etc...
I did a quick sketch trying to keep the main ideas but showing how the lighting is missing in your piece.
If you get the light right then you have a sense of the painting being a representation of a real 3D object as opposed to say something flat. The other stuff like material definition can fall in to place afterwards.
Oh and if you want to watch me paint live I recently got introduced to this thing called picarto TV... It's nice to do art and share it - if you have any questions it's great to talk too! I'm painting pretty much 12 hours a day so you'll most likely find me - unless I'm eating
