Isn't fun to change your work, without breaking a sweat? Photoshop is great for playing around with different textures and help me see what I can come up with next. I did this quick little sketch for my daughter on plain sketching paper and watercolour pencils (left) - It looks a lot more interesting with the fake canvas texture (right) which I added to the scanned picture. I like my little sketch a lot better now: it's tougher to use pencils on rough textures, but the resulting work may be more appealing.
