Heres how I do blood. Start with red mixed with black. Thin it down like a wash a dab it where required. Dont cover the weapon less is more. Now highlight the blood with dark red then red. Make it look like its splattering. Keep at it. Nice paint job
don't worry and keep it up. Try amking more layers on bone parts, and a subtle black layer on he part you want to look bloody, this wil make blood seem more gory.
