hi Mechaform,
welcome and thanks for taking the time to talk to us.
my first concern is the head sculpt, its too long and not round like all g1 versions - he looks like an old man
i also agree with sinnertwin that the grey elbow joint breaks up the colouring of his arm too much and its preferable to be white.
he does look very tall and lanky though, i've noticed the thighs looks very hollow and there because the is a gap between the hips and chest, it accentuates his lower torso as being too thin.
lastly i am not liking the legs at all really. the dont look very nice and it looks like there will not be much articulation in the knees or feet.
if this product is going to be the size of the Takara/Hasbro MP line, then it needs to fit in more with the aethetics.
here is a photo showing what i mean.
Fantoys' Quakewave when compared shows how close to design style they are. And I would much prefer a bulky but well proportioned Jetfire/Skyfire than a tall, gappy one.
