Welcome to the Guild!
Though the majority here are digital only created maps, there is a strong core of hand-drawn mapper, including myself, though I do both styles. The only Runequest I've ever played is the first version, back in the mid 80's.
There are a few hand-drawn only tutorials, but if you're using Photoshop in addition to traditional methods of coloring, explore the tutorials section. While I too have CC3, and don't use it much, there are CC3 users here that create maps that others assume were entirely created in Photoshop or GIMP as they distinctly look more artistic/hand-drawn than CAD created. Its worth looking at stuff by Gandwarf and others.
You're in good company, show us what you've got - even those crude older maps you claim lack artistry, yet are still functional.
