Fantastic Model. What an excellent addition to your army
1. Excellent photos....very crisp.
2. Good use of the yellow/blue/red primaries for the details.
3. Great metals (3 recipes I think) and Leathers (2 recipes I see)
4. Solid execution of a color scheme. Very orky yet not overdone. THIS IS A SUPER JOB.
Recommendations but certainly not needed:
1. Skin could use one more layer - dramatic highlight thinned on knuckles, muscle tops and face (the face is very prominent on this figure and most orks)
2. Eyes need some love. Looks like just a dot of blood red which doesn't do the rest of the model justice. I'd do a small dot of orange/yellow mixed on top AND/Or a little controlled wash of Red Gore w/ a touch of black around the eyes.
3. Practice or Learn some black lining to help define volumes. Areas of that could be improved by this technique. (note: this can be done well after painting and sealing so no hurry. I'd be glad to help.)
a) around the tooth and upper to lower jaw. Helps further define the face.
b) leather straps.
c) around small items trinkets to pull from waistcoat or other areas.
Area of improvement:
Matt said it...the base. Now if this was a trooper you wouldn't hear boo about it . But this model is very well painted and nothing sets off a great model like proper basing. The blues on his toes would be Knock outs on some PVA/Sand or if you don't want to do one yourself or even purchase a great resin base.
If I'm going w/ Flock I tend to sprinkle just a bit of grey ballast on the PVA prior to dipping in the flock. Works wonders to break up the single color.
