Nice pictures comrade.

Id have to say the first enemy picture seems to be a poe, though I might certainly be off...

As for the second it likes like some sort of Chu, but once more I don't know.

The Hammer is a bit odd looking, but it doesn't look too bad and with slight alterations you mighty have it brillantly done yet! Though, one suggestion would be thickening the whole handle, then making the crips about the size of the large handle as it is now, so as to add mass to support the heavy hammer head.

Just a suggestion.
