Is this part of a set?
The 'Red Slope, Curved 4 x 2 with White and Yellow Flames Pattern Model' part (right side of the picture, on the roof) comes in 2 variants: Left and Right.  However, both of these parts only exist in the same 1 set, 9441: Kai's Blade Cycle

Similarly, the 'Tail Shuttle with Lightning Pattern' (left side of the picture - also comes in Left and Right variants) come from 9442: Jay's Storm Fighter

(This also appears to be where those 2 large blue plates are from)
As such, this model must be a Maker's Own Creation (MOC), and not an official LEGO set.  So, yes, a 'random build of something'
Both of the sets listed are from the LEGO Ninjago: Rise of the Snakes series
