Maybe it would be better if you made it more like a fight between 2 persons. Now you have one hand, always dressed the same so clearly belonging to the same person, while it does look that there is some interaction because the eye poke guard is protecting from the eye poke. I don't know if I am making myself clear here?
And the image itself is a bit boring maybe. Try putting some more movement in it, maybe drawing it yourself instead of using photographs, I don't know... and get rid of the baby blue? Maybe brown would do better...try some other combinations and you'll get there!
Needs work, but it's a good idea to start with so: Good luck!
And I hope you'll get some comments from others too!
I think it's hard to 'read' as it is. in terms of composition of objects, they are nicely arranged, but it it hard to unscramble in a few seconds.
For a start - the you might want to change the colour of the cuffs from the eye-poking hand to the eye-poke defence hand to show that they belong to different people.
Perhaps scrap the left handed slap and add a 'Backhander' and perhaps a variation on the punch - like 'rabbit punch' or a 'horsebit' knuckle pinch.
Make the concept more a 'Slap-stick Guide To Self Defence' and give the arrangement more order - like 2 columns, with the eye-poke sharing two columns at the bottom? Just some food for thought! I love the idea though and love the style you've gone for.
Ok so this is STILL A WIP. I'm gonna add different hands. Perhaps play a bit more with the shirt of each character. But its more or less the overall picture. Do you guys think it works better? Should I keep the text?
I honestly would like to see line art, which you do superbly, of the hands, giving it a vintage advertisement feel, like clip art but not clip art. Also with hand done writing and dotted lines, etc.
