@tabletopminis I was told I should post here by @ReadyUser31
I'm new to painting miniatures, but I've been playing DnD for a long time. Recently I've been 3d printing and painting my own miniatures. I'm not great at painting and unfortunately I'm trying to keep pace with the campaign I'm running. Here are some examples.
Vallejo makes really good paints. Game Color is another good company.
They can be expensive, but they last a very long time and look great. I purchased a 75 color set of Vallejo, when my wife went full in on painting, 4 years ago. We still use it today. It was expensive, but I've not had to invest that much since. Just replacing the more heavily used paints once in a while.
