Gesture Drawing: There are plenty of websites that have been created to be gesture drawing generators. They give you options to select genders, clothed or nude, and a time period, and will cycle through images for you to draw. Some of the ones I have used are:
Anatomy: Yes, there are hundreds of anatomy tutorials on DA, but there are various other websites you can use as well.
- www.posemaniacs.com/ - This site has a selection of 3D generated models in a variety of poses, that show the muscle structures. You can rotate the models to see the poses in different angles as well.
- teachmeanatomy.info - Here you can find technical diagrams of the parts of the body, showing muscles, bones, organs, etc.
Color: There is more to art than just the drawing, here are resources related to color.
- kuler.adobe.com/explore/most-p… - Here you can browse preset color palettes.
- colorschemedesigner.com/csd-3.… - Use the color wheel to select a color you have used in your artwork, and it will give you colors that will go well with it.
Perspective/Architecture: They are harder to find, but there are still resources that can help you with perspective and architecture.
- www.sketchup.com/products/sket… - Google Sketchup is free and especially helpful. Build a single building or even a whole city, then you can move around it to pick a location/angle to draw. It is particularly useful if you draw the same locations often/at different angles (like for a comic), because you can save your city, house interior, etc and move around it freely for different views of the same place.
- technographer.com/projects/gri… - a perspective grid that can be manipulated. You can zoom, roll, change field of view and elevation, etc.
- www.artyfactory.com/perspectiv… - Crash courses in different types of perspective, one two three point, aerial, circle, etc.
So, I hope you found this helpful. Please share/favorite if you did so that more people can see it, and if you have any suggestions leave a comment and I may add them to the article.
