So I have finally begun painting my first model. Really excited.

UPDATE (Jan. 24, 2013)
--------------------------------------------------------------------------------------------------------------------------------------------------------
I tried washing the original model I painted but it turned out terribly. I have now painted another model, and instead of washing right away, I first laid the basecoats of all the main colours. I'm very happy with how the Guardian looks now (especially considering it is only the second model I've ever painted

)
See below. Do you guys have any advice on what I should do next?
To properly view the picture, after you click on it, press the zoom button on the Photobucket website, then once the full-sized picture appears, right click on it and press VIEW IMAGE. That way the picture is not zoomed in so far and you can clearly see the whole picture.
