You could do the one on the left, and it would look gorgeous. It would be similar to maps you have already done, which is fine.
The one on the right would allow you more options and, yes, would likely involve more experimentation.
The left one could aid in more mastery of style.
The right one could aid in more expansion of skills.

I suppose it depends on the amount of time and effort you want to put into this map.
Me personally... I'd love to see what you would do with the one on the right.
but... experimentation should be fun and light-hearted. Not weighty and draining.

I'd also love to hear any bits of story that may relate to your lands, as you go along.
