Found it more legible on 5th than 4th (although 1st could be interesting (+ the dog bitting some foe or something on back ?) if you extend your illustration on right).
But do the one you prefer of course !
I'm fond of the stance and graphical aspect on 2. Perhaps in an environnement and perspective like 4,5? I already imagine your character striking a homerun and the dog is ready to fetch the ball (the ball is a foe's head, of course).
3 is rather fun but we don't get the superpower.
Good luck!
Thank you all 
for your comments and your support! I think that option 4 or 3 or 2... 
. I still need to think before making the right decision)))
Guys ! After much deliberation and reasoning, I chose option 4)) It seemed to me the most successful and revealing the topic)
A solid choice!
Thank you 
The concepts are doooope! I look forward to seeing the finished piece!
Thanks) I will soon finish the final drawing and will definitely show you what happened, I'm afraid not to have time ... very little time left, I hope that the organizers of the competition will add a little more time))
Yeah, I'm cutting it close too and we already had an extension. 
Hope you finish in time too!
Awesome, love the jaw on the dog. And the two finger grab on the guys collar is a great touch.
So much action going on, great job! I think you went for a good composition choice in the end, though they were all fun.
Hello to all! Thank you for your support, it helps me a lot. Good luck to all!
I'm starting to paint with color, for now the draft version ... the process goes on, there is very little time left
Rendering .......render not complete
I will do the final rendering of the illustration and concept sheet
