So continuing on the last sketch, I decided to colour it on Photoshop. Drawing the base colour and filling it with gradients of lighting and shading is quite fine, but then I realized that with the black lines, it looks grungier than I expected, so I decided to just put gradients on lines directly.
So I decided to put some gradients on the black lines to make things seem like glowing. the problem is, It is very tiring and tricky to make sure all the black pixels are selected while using selection tool and lasso, and by then, I seriously grew tired. So I’m tempted to just drop it as it is. I guess some practice in lighting and colouring would be needed.
