The scene (roadside) is encumbered with signs
The blur on the wheels is not radial and not aligned to the proper axis
The face of the rider is somehow too clean, too stylish, too... un-post-apoc
The bike is an old-timer, but the setting should be based on avant garde future visions of the old times (1950's/60's)
The white lane mark doesn't belong there, it would've been lost since many deathclaw generations
The first loading screen looks much better (although I would scrape the Nuka Cola sign)
Just my two eurocents.
