I like the pic (no duh)
but, the coloring isn't so good. Ever since mizu posted her tut, everyones been trying to color and shade like her. You pol don't have to copy exactly the way she does it. Come up with ur own style, and impress everyone...
I don't have big bag with experience about colouring like some other members do , but this is what I can say...
You could have coloured whole page , with no cuts , like it is =)
You must be registered for see images
Then, there would be no need for that Lens Flare . In my view that flare don't fit ^^ Good background would do the trick , but I see original pic had only white background with no details... so making one would mean more work. But anyway , great colouring = lots of work =)
And as NarutoGoku said , "...ur own style" If you continue colouring you should "Come up with ur own style" =)
Btw, how many colourings you have done so far ?
Suggestions :
1. Next time pick a manga page with detailed background ^^
2. Throw away that Lens Flare xD lol
That's all ^^ Good Luck ,Have fun with colouring =)
