Digitizing and colourizing

After mentioning about moving into colouring my illustrations digitally and now having a solid colour palette, I did some template drawings here which I photographed and altered to look as if they were digitally drawn. In Photoshop, after boosting the contrast up to solidify the black lines, I simply used the paint bucket tool to fill in those areas which needed to be coloured. The comparison between original and coloured version can be seen below. I was uncertain about how the outcome would turn out, however playing around with various paintbrushes and adding some shading here and there, I quite like the end result. In an ideal world, something like this would be drawn first in Illustrator and then either coloured there too  or moved in to Photoshop, however since I don't possess Illustrator, this will have to do. And, in actuality I think this combination of traditional hand drawn and graphics works better as you can see the patchiness and rough penmanship in the outlines which gives it a more personal touch.
