I'm a fan of the dip as well! I'm not a great painter and used to get very frustrated when I couldn't get stuff to look right and then give up. I know the result is still far from perfect compared to people that really know how to use a brush but for me dipping has really helped me improve my models and speed up the painting at the same time.
Here some examples of my beastmen that were dipped (you can see more pictures following the link below):
Some things that I learned and might be useful to anyone trying out dipping:
- Apply the dip generously with a brush to have more control. Let it sit for a minute and then remove excess blobs of dip with a spare brush
- I always use white primer to help the mini's not getting TOO dark
- i do some basic highlighting before the dip and a bit afterwards to re-highlight
- experiment a bit with the basecoat colors. It's usually better to use a color one (or 2) shades lighter than usual coz the dip will make it look like a darker color
- the dip I use (strong tone) works best on brownish/reddish/natural colors (so perfect for my beastmen!). Grey is a color I couldn't really make look right with the strong tone dip (dark tone might be better for that but I've never used it)
