Urbansketch: Mountain Tree

I started sketching urban drawing from this week. And today I thought I should experiment with the marker pen and the urban sketches.

So the object here was mountain tree. It was near the barn field. So I thought I should be taking that into perspective and draw the object.

Marker usage was not planned. But I thought I should add and experiment. I wonder if only one color would suit or should I go with one or two color at the most in future urbansketch.

I'd appreciate your feedback if you are into urbansketching and have any advice on the art. :)
