Here are some Adobe fun I have done. Not the best I know. Just testing possible characters I want to see.
When I first saw that skywarp one as your avatar I thought there was an auction I didn't hear about. Sort of spoilers: Is that a show accurate color scheme on him? I tried not to pay to much attention to Magmatron's spoilers so I haven't saw him in jet mode.
That is what I thought of doing to Lockdown when I first say the ALT mode. I would shave the spikes off and try to find a decent spoiler or build one out of Styrene. As for bot mode just putty his face a lil to make him more heroic and presto Hot Rod/ Rodimus.
