I am absolutely convinced that there is a point in the painting of most models where your output looks "disappointing" and not how you envisaged that it will turn out.

However, I am equally convinced that this is just a "hump" you need to get over. It usually occurs around the base colour, first highlight stage and you feel like giving up. You then apply a wash or a light drybrush or maybe a second/third highlight and suddenly the figure "pops". It's at this stage, I find anyway, that it goes from being a model to part of your army.

If you run into this "hump" - and I don't believe I can be the only one who experiences it - I find that focusing on the face or shield will give you the kickstart to progress with the model. Suddenly it gets some personality and you have the drive to finish it.
Do others hit this "hump"?
