Strong Points:Clean, Variety of Techniques, Strong Gesture

Weak Points:Helmet

Recommendations:If I was being picky, which shouln't be necessary as it is as you said a quick sculpt. But if it was too be pushed further, I'd maybe spend a little longer on the helmet, just strengthening and cleaning up the lines.

Strong Points:Nice and clean, very interesting face and detail all over.

Weak Points:Lack of detail on the armour and head piece.

Recommendations:I would add some cracks and scars on the armour to add to the realism.

Strong Points:Design of face and placing of beard is good, size and proportions work well.

Weak Points:Lack of detail, need finer spores and wrinkles to help with age and realism. Helmet is too blockly needs battle worn details perhaps add some traditional patterns to set him in place. The connection with the helmet wings could be better modelled in, at the moment they look stuck on with glue, think about metal construction and how they would have welded such a heavy piece to the helm. Although the helmet is cool if you take his hair out youll see its actually too small for his head and would only protect his cheeks, looks great but perhaps extend it further down to protect is neck and jaw? His chest armour needs alot of attention, each metal disc should have a slight variation of the next to lift it from a pasted replicated feel. They look really nice but for realism you need to bevel the edges and finish the connection with the sleeve, some of the discs just dissapear. The discs that hold his cape needs some damage love too, just too perfect. Also the cape should be a bit of a feature but is sunken under the weight of his hair, perhaps push the hair up and build a really nice strong cape it will give your sculpt a much stronger and ore powerfull feel.

Recommendations:Perhaps do some more research on Odin and check out all the awesome character art thats been done for him especially his eye patch and helmet, I had a little look before I wrote this and wow there is some amazing stuff.
