One thing that can be easy to do, especially with Dynamic topology, is to get too focused on details too early.. making something look really great when you’re zoomed in, only to realize when you pull back that it doesn’t fit with the rest of what you have. Work in stages. Try to get all the large forms in first before going in for detail. Once you have those in place, work on your secondary level of details, getting all those in place. Then refine further and further as needed.
Exactly when those “stages” are will be up to you and depend on the project, but you’ll have much better results working like this.
One year, I did a 30-day challenge where I spent about 30 minutes sculpting something. The idea was 2 fold… one to get me doing something (because it’s easy to find half an hour to try to do something) and the other is that the quick amount of time forced me to work on larger forms first. 3 of my favorite sculpts that I’ve done have come from that… a dragon, a turtle, and an elephant. I’ll use them a lot as models for textures and such when I want to play around with procedural textures and often use them for lighting exercises as well, or as figurines for rooms I’m doing..
