Superb.... these are are all pretty spot on, with the current styles for each team, trouble is the clubs themselves could do better, the cowboys for example the generic navy jersey with a few stripes, they need to get more of that silver/grey involved, just like you added the gold to the dolphins just then
Melbourne has its purple... tigers have their orange, eels have their gold, Newcastle needs more red and possibly add silver to their blue jersey, and warriors need to create a green jersey with their blue... gold coast should be gold, they had one some months ago, it looked fantastic, otherwise the designs are great, but they aren't any different to whats existing already...
The dragons home you just made could do with something at the bottom like those dolphin lines you added maybe inverted tho, so it fades to the white up top, that will give it some steeler vibes having white lines and the red torso
Something like this
(i know its terrible, its on my phone app)
