Hey guys, thanks so much for the feedback. Einion, I should actually say these are my 3rd and 4th figures as I stripped my first one and started over... so I'm definitely familiar with that concept.
I've been checking out the SBS's and have a bunch of books in my collection already on the subject and there's just so many different techniques at this point I'm just trying to get a method that I can get comfortable with.
I was having the hardest time with layering acrylics until I read your post, Tony. Not sure why but it finally just clicked and I've had some good luck with it (I've primed a couple toy action figures to practice on). My Hulk's pecks and abs are very nicely highlighted right now... haha.
I'm still trying to get that same "click" to go off with oils though. Using them as diluted as you mention, Tony, seems so counter intuitive to me for some reason and I find that I'm not building any shading and that I end up just getting the area wet. Acrylics dry fast, so I am able to layer them as described, but to build layering in the same fashion w/oils is just not working for me yet... I still find myself wanting to place a less thinned bit of oil, or even a dab of straight oil and "pull" it into the area and blend/stipple it in. But, I know for sure, especially on the figures above, the oils are way too think.
Short/medium term goals for sure are to just to get comfortable with a specific technique and go from there and get these layering, blending and feathering to at least a competent level. At that point I'll worry about more advanced techniques and styles.
In any event, thanks so much for the feedback, it has been a great help. I get the impression this forum is for the more advanced guys but, I wanted to get some harsh (in a good way) feedback and I appreciate it much! I will definitely keep spending time in the Painting/Beginners and other forums for more tips and tricks.
