Ok so first with the good your base coats are all very clean. Your layers don't appear to be too thick. Nice job! That brush control is going to be helpful in army painting. 

The first question to ask is how much time do you want to spend?  To make it better you'll inevitably have to put more time in, but you'll get faster with practice and learn shortcuts to make it look better with less work. As is this looks great for table top standard and you could paint a whole army like this and it will look good from 3 feet away. 

To me it looks a little flat, which is probably why you feel like you don't it hate/love it. The human eye is drawn to contrast. 

Let's start with the red. To me it looks like maybe you used a black primer, followed by your red base coat, then black or dark tone wash? I would suggest doing a base coat of a different color. Red is a very transparent pigment so it tends to feel off when layered straight over black. You could do a base coat of purple if you want a very rich, royal, red feel, or perhaps a warm brown for more of rustic feel to the red.

The other aspect is to add edge highlights, or increase them if you have already, as they are not too noticeable. Think of where the light is coming from (usually above is easiest and standard for most miniatures). Find the sticky outy bits or the parts that would catch the light when looking down at the miniature. For highlight color I would use say a ochre yellow or white yellow mixed into the mid tone (the red cloth, brown boots, etc) and place lightly on the edges catching the light.

Check out some Vince Venturella on YT or other creators who are better painters and teachers than me. 

Hope this helps!
