Thank You all for Your comments I believe making Grimlock with accurate vehicle mode would demand building the whole thing from scratch. You can always have a look at Titanium version and try to use some of its ideas.

I wish I can make Grimlock's vehicle mode but I don't know how .

Awesome work, dude.

This looks great. I like the new proportions a lot, and the paints are really nice too. Great stuff.

Thanks for all the comments blaynescott - I have written all the details in the description. I've been looking for the right legs for some time, because stock ones are really poor. I have decided to use legs of leader class Animated Megatron. They will fit almost perfectly. I also used the knee joint. You just have to switch all the bottom part of the leg. A few minor modifications and everything will fit perfectly If You have some more questions feel free to ask. P.S. Downscaled MP Grimlock head Would be great. I didn't have one so I resculpted Hulk - after all war within had a little bit different head... I would love to see your Grim when it's ready

Neat. Where did the legs come from? Are they 100% styrene work, or appropriated from another similarly-scaled TF?

I have something similar in my unfinished bin of customs, using a downscaled MP Grimlock head. I'd love some suggestion on how to overcome the stock legs/cannon turret.

COOL!!

This awesome!

This is so COOL! Love the paint job!

Looks pretty cool!
