The possibility for a self-consistent description of all the basic featuresof the observed cosmic ray spectra and primary composition variations in theenergy range of $10^{15}\div 10^{20}$ eV within the Galactic origin scenario isexamined.  We assume the existence of Galactic sources that accelerate particles up to$\sim 3\cdot 10^{18}Z$ eV and take into account a highly inhomogeneous(fractal-like) distribution of matter and magnetic fields in the Galaxy thatleads to extremely large free paths of particles ("L\'{e}vy flights"), alongwith an overwhelming contribution to the cosmic ray fluxes observed above $\sim10^{18}$ eV from particles reaching the Solar System without scattering. Ourscenario was refined on the basis of recent experimental results on primarymass composition. Model predictions, which could be verified with the improvedhigh-precision measurements in the nearest future are discussed.
