Here is the coloured version of the WIP submitted some time back.

I am not happy with this piece. I will say that first.
Why?
1) Girl's eys are accidentally yellow.
2) No classy shading.
3) Poor backgrounds.
4) Lifeless characters!
5) Poor colour combination.
6) Poor colour blend for centre lines.
7) The lady's fingers looks as though she was just eating Twisties!

Well, the only things I'm actually happy with this are:
- Colouring of the punching bag.
- Physique of man and lady.
- Colouring of Man and Lady (minus the lady's eyes)

I based the looks of the people on a number of people/clothes, so I must at least make a mention.
I used my sister's hair on the lady, and gave her the red socks my sister uses for training, as well as a pair of sports shoes she owns. The shorts design on my own PE shorts- yellow and navy blue, but I though the colours of Germany sounded nicer.
For the man, I used my brother's grey singlet, and his finger-less "working out"(because I don't know what the leather gloves are called) gloves. For his hair, I borrowed Lawrence's. As for the shoes, I took inspiration from my friend's, Deborah, or Debbie as I sometimes call her, sport shoes.
For the man's overall look, I actually took inspiration from Shan (the DJ working at Power 98 FM).

My viewpoint for this would be that you can be tough, no matter your location, your origins, and (especially, I guess) your gender.
I did many contrasts in this, because...
Well, I haven't thought of it, but do let me know your views.
