I agree, this is an excellent 'Mech! You managed a believable but appealing colour scheme. I agree the base is very plain but it's tough to base 'Mechs, for scale reasons if nothing else.
WOW....this is one of the best Mechs I have ever seen. Great color. The base is dull but it may add to bring out the minature itself. These darn things are hard to make look good, but you did it!
