Did not like the front of the last sketch when I saw it the next day so did a few more ideations and changed the proportions a little. The bigger one is my favourite ( similar to the one below, just did the front light area slightly thinner and added an oppening down+ did a bit of refinement of surfaces)
Now will spent some time with sketching and developing the concept more. The side perspective will be the key I guess.
More to come...
