Lost, it's clear you're competant in photoshop (or whatever you're using), but you clearly need to work on your understanding of geography and of composition. Simply put, if you're able to produce a parchmenty look like in your last pic, there's no excuse for confusing messy lines or entirely random land masses. Sadly it does look like you've just put on some irregularly shaped blobs to fill gaps in the sea, without any particular reason in gaming terms, nor any logic in geographical terms.
Land masses in reality are very complicated. Look at some maps. See how the coasts work, how they relate to mountain ranges and how those relate to islands, where deserts and forests form in relation to each other, and so on. Google things like fantasy mapmaking. I am certain you'll have better looking land masses with a little research.
