Welcome to the Guild Pop! Well you have certainly come to the right place to discuss map-making and fantasy worlds. As to your WIP map of the super-continent, the hand drawn style looks good so far, and the parchment is appropriate, but the blue is completely out of sync with the hand drawn style. My recommendation would be to stick with a parchment background throughout the map, and either make the water slightly darker (e.g. by creating a water later, coloring it black and then lowering the opacity and changing the layer mode to "overlay") or by creating wave to surround it, or both. At any rate, be interested to see this develop. You may wish to post a WIP of this up in the Regional Maps section where it will receive more views and thus more constructive feedback.

Cheers,
