I just posting drawings I am working on, and if anyone has questions or comments, go ahead and give them to me. My art plans are in my head and sketched out on a layer not shown, but if you would like to see something different just say it.
All of this was drawn in photoshop.
When I start out with a room I imagine what I want, and use my favorite tool (Polygonal Lasso Tool (L)) on a new layer and fill it with color. I do that for each wall. On these walls I drew lines to mark were I wanted to draw the stones. I hold the shift key to make the lines. The stones are on a new layer for each wall and to blend them together I use the top layer to draw on.The window was just a matter of selecting the area filling it with white, then selecting area for lines and drawing them in. I like to work by selecting each surface and drawing what ever I want in them like the work bench edges were one selection and the top was another, but to make the edges I use the marquee tools. After I finish I add a layer to blend some of the edges. When I drew the top I draw the grooves to make them boards, and added some grain. The bright area lit by the window is another selection but I used Feather on the Lasso tool and copied what I drew and paste it back in. Then I used brightness and contrast to make it look like a bright area. Drawing each stone was a little hard, but it looks better. they don't have a lot of highlights, because I don't want to have highlights on stones in shaded areas. So, I do that on a new layer when I draw the shadows from the work bench. If you try drawing like this and get use to it you will find just drawing what you want can be very quick. Why I use layers covers a few good reasons:
Every part of things I make a layer so I can draw each piece. Some parts may go under the other part so there are no cracks at the seams.
If I feel something is finished and I want to add something to it, even highlights, I start a new layer. Then I always have a option to edit, add layer effects or fade, and only effect that layer.
If a surface has an edge and it is not a simple color but has wood grain or texture, different highlights or anything I make a new layer.
I am free with layers, and if I wanted to find one in many I right click over the area with the selector tool and a list of everything in that area will show up. If it was named that makes it easy.
On this I drew each tool. Like the push drill the handle and the shaft were drawn separate. and when it was finished I merged the layers, then added the shadow. I link those together in case I move the tool.
