Well it was ok...
For 1 you used a impreza
2 I could tell you didn't have Comfort Hards on so you could have gotten much mor angle and you were more power sliding the corners (mainly cause of the 4WD car)
Just keep practicing and try switching to a FR or MR car cause a 4WD car isn't technically drifting and it also doesn't take much skill to Power slide a 4WD car
I would recommend starting off with a Lil Silvia s13 or maybe a nissan 180,200or 240SX (the only difference is whether it's RH drive or LH drive)
My buddy is also starting off with a G27 and he prefers to use a FR Skyline GTS (R32) but he kept it stock except for the suspension
And never judge yourself based on what people tell you, base yourself on how hard you practice!
