Hi Samuel.
While a basecoat, wash and drybrush does work on 1/35 scale, when these techniques are mastered, can actually suffice, the end result is rather limited.
One of the best learning experiences I had with figures was to attempt 1/16 figures, where all has to be actually painted. After 2 figures at this scale, it was easier to go back to 1/35 and actually "paint" the figure.
Another useful experience was to follow step by steps from magazines where talented modellers explained how they paint. Even if it does not always work out, the experience and lessons learnt all help. There are several such articles here on Armorama.
Another tip is try different mediums .. oils and enamels. (For enamels, check out Mark Bannermans articles on Missing links). Working with different mediums gives different results, finishes and also makes you more aware of how you´re painting.
By your description of tiger stripes, your wash does sound as if its not properly thinned. Its better to wash several times and build it up, rather than try to get it all down at the same time. If you used acrylics, steeping them in alcohol/windex will lift the paint.
