Hello Brandon,
In search I accidently got this site and I think I’m thankful for it. I am an Interior Designer staying in Oman from past 5 years. Here there is no source for any new knowledge and information as well improvements. Here people go more for photorealistic works. (May because we r neighbor of Dubai). But still my some clients and I prefer hand sketches and rendering for concepts.
I did one project for the architectural firm. I did concept and then layout in Cad- and made Perspective by hand, drawn on A2 paper, n then little basic water colouring and then in Photoshop.
But I want to improve more.. in my hand perspective. It’s my strong point, and coz of daily designing work with computers it’s becoming difficult to be in touch with.
I would like learn Piranesi and some Architectural hand rendering techniques and about Copic markers as I learnt about it on your site (Here we don’t have source for anything like that) as I stay in Oman.
