Thanks guys. I don't want to dwell on anything here besides sketches, but one post I always remember is this one below, from the "Vintage Concept Sketches" thread in the sketching forum:
Are these styles still appropriate for a student to use now-a-days?
a drawing is about communicating an idea. I think the style should be dependent on what communicates your concept the most efficiently (both in terms of time and impact)
I think it's very important to experiment with other designers' styles, and then mix and match to see what works best for you, to communicate your ideas. For me, shading with the side of a blue pencil is the most efficient way to communicate volume and form, especially in quick ideation sketches like the ones in my previous post. I will admit that I learned it from Michael, but again, I don't see any wrong in that, as I have found it to be a very fast way to communicate my ideas on paper. At the end of the day, it's about the idea/design behind the product-- although sketches are an important part, they are just a small portion of the process to designing a good product.
Anyway, I have been working on a more finalized rendering of my concept. I'll post when finished to keep this thread goin...
