New mapper? Welcome aboard!
This does have some of the usual things for first maps - never mind, that will come with experience. The important thing - the ideas - are there!
I'm looking forwad to the next map, and i expect to see more details, less up-and-down walls... and perhaps a less intense monster population; i was never a fan of rush-hour maps... (said the grumpy old sod!)
Very nice for a first!
