Advise for Hand Painting?

[Amalynn]

So my last two projects have been hand painted with a brush and Vallejo acrylic paints as I don’t have an airbrush or means to do any spraying with a rattle can or airbrush anyways. I’d like to hopefully change that sooner or later, but in the meantime I have been painting by hand. I’ve produced serviceable results but I‘m not as happy with the final products as I could be. What sorts of advise can you guys offer to improve the quality of my painting? Are there any particular products you guys would recommend? What’s your workflow look like when you do hand painting? Literally anything would be incredibly helpful.
